I get something like this after 'make modules_install':

if [ -r System.map ]; then /sbin/depmod -ae -F System.map 2.6.5-rc3; fi
WARNING: /lib/modules/2.6.5-rc3/kernel/drivers/net/irda/tekram.ko needs

Thanks for this report, and sorry for the late answer.

drivers/net/irda/tekram.c uses irda_task_delete, but this function is
not EXPORT_SYMBOL'ed in net/irda/irda_device.c .

The most simple solution would be to change TEKRAM_DONGLE_OLD to be a
bool (as does the patch below), but perhaps the IrDA people know a
better solution.

Say Y here if you want to build support for the Tekram IrMate 210B
dongle. To compile it as a module, choose M here. The Tekram dongle
